In high-performance CNC machining, every second and every tool change counts. Minimizing downtime and preventing equipment damage aren’t just operational goals—they’re essential for maintaining productivity and profitability. One often overlooked factor in achieving this is reliable spindle monitoring during automatic tool changes.
Why it matters:
Missed or incomplete tool engagement during a changeover can lead to:
- Costly spindle damage
- Unexpected machine downtime
- Lost production output
Fortunately, innovative sensor technologies now make it easier than ever to monitor and protect your CNC spindle systems.
